commit 0dff3f98c0fbcc755e76a7f6ea20d3a2ff2eebbe Author: Nick High nhigh@openmailbox.org Date: Tue Apr 26 17:22:05 2016 -0400
nb/intel/gm45: Fix native text mode initialization
The LVDS port is configured to accept data from pipe A, but the panel fitter and VGA were attached to pipe B.
Changes to VGACNTRL: - select pipe A instead of pipe B. - disable VGA centering to fix jitter.
